I had a customer in this weekend with a papyrus she needed reframed. It was originally framed at our store a few years ago, by someone no longer working for us... Anyway, the former employee told the customer that papyrus should be framed with "double glass". Let me elaborate... starting from the front, it was glass, mat, papyrus, 2 ply backing, glass, paper dust cover. There was no decoration on the back of the papyrus that would need to be seen when finished, and it wouldn't have mattered anyway, since the papyrus was backed and the glass on the back was covered by the dust cover. I can not imagine why a papyrus would need to be framed this way. Any ideas?
